The first suggestion that came to my mind was Wednesday, from The Addams Family. Come to think of it, though, there are also other words/names from that... (Uncle) Fester, Lurch, and Thing. (I would have said Cousin Itt, but apparently his name isn't spelled quite like the word.)

I don't know if you would count Fester, Lurch, and Thing as words/names that belong on this list... but some "real people" do have names that are also days of the week. According to Wikipedia (which I wouldn't cite for an academic paper, but I figure it'll be okay for this) :

"Wednesday, whose middle name is Friday... Her name appears to have been a satirical reference to contemporary actress Tuesday Weld."

Also, I'm rather amused by this list. I do, however, wonder why you chose "I don't give a damn" as its name. ^_~
